Title:
NIFEDIPINE-METOPROLOL SUSTAINED-RELEASE COMPOSITION, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/247952
Kind Code:
A1
Abstract:
Disclosed are a nifedipine-metoprolol sustained-release composition, a preparation method therefor and the use thereof. The sustained-release composition overcomes the huge differences in the solubility of the two drugs of nifedipine, a pharmaceutically acceptable salt or solvate thereof, and metoprolol, a pharmaceutically acceptable salt or solvate thereof, the two antihypertensive drugs with complementary action mechanisms are prepared into a daily long-acting compound preparation by means of a single-chamber double-layer osmotic pump drug release mechanism, so that the two drugs achieve long-acting synchronous release, and the 24-hour cumulative release degree of the two drugs can reach at least 85%. The sustained-release composition has a stable preparation process, convenience in terms of production and a conduciveness to industrial production.
